Comparison of the Implementation of the Mamdani Method and the Sugeno Method in Predicting Green Time at Intersections Based on Vehicle Volume and Lane Width

Abstract

This research aims to examine the application of the Mamdani fuzzy method and the Sugeno fuzzy method in predicting the duration of green traffic lights at the intersection of Patung Pangeran Diponegoro. Data collection for this study was conducted through direct observation at the intersection of Patung Pangeran Diponegoro. The conclusions obtained are (1) The results of applying the Mamdani method in determining the duration of green lights at the intersection of Patung Pangeran Diponegoro in the morning are 40 seconds on Jl. Soedarto, 63.8 seconds on Jl. Setia Budi Selatan, 33.7 seconds on Jl. Ngesrep Barat, and 47.5 seconds on Jl. Setia Budi Utara. (2) Meanwhile, the Sugeno method in determining the duration of green lights in the morning amounts to 34.8 seconds on Jl. Soedarto, 70 seconds on Jl. Setia Budi Selatan, 30 seconds on Jl. Ngesrep Barat, and 40 seconds on Jl. Setia Budi Utara. (3) The results of applying the Mamdani method in determining the green light duration in the afternoon were 36.8 seconds on Jl. Soedarto, 63.8 seconds on Jl. Setia Budi Selatan, 33.7 seconds on Jl. Ngesrep Barat, and 63.8 seconds on Jl. Setia Budi Utara. (4) Meanwhile, the Sugeno method showed 31 seconds on Jl. Soedarto, 70 seconds on Jl. Setia Budi Selatan, 30 seconds on Jl. Ngesrep Barat, and 70 seconds on Jl. Setia Budi Utara in the afternoon. (5) The resulting MAPE as a measure of accuracy was 15.5% for the Mamdani method in the morning and 7.5% for the Sugeno method in the morning. In the afternoon, the MAPE for the Mamdani method was 10.25% and the Sugeno method was 9.6%. It can be seen that the MAPE value for the Sugeno method is less than that of the Mamdani method, thus concluding that the Sugeno method is more accurate than the Mamdani method in determining the duration of green lights at the intersection of Patung Pangeran Diponegoro.
